Thank you! Rabbits can only do something with your help, so don't underestimate your impact.
Most likely this feeling arose because you only played the first tutorial levels. Play the later levels of the game, especially 10, 11 or 12. In them the feeling that you have done something is much higher. You can reach this levels by using special "skip" button on the right of "start" button.
Hope this will change your mind about your impact in our game!
